Some pretty great resources I've found for learning Ember (which, surprisingly, can be really difficult with the pace things are evolving in the Ember world).
- EmberWatch - a compiled list of talks on different things related to Ember.
- Ember Observer - a bunch of addons for Ember
- Ember Weekly Newsletter - a great email newsletter with news, tips, and talks on all things Ember
- ember-cli 101 - an awesome book in the style of Michael Hartl's "Rails Tutorial". diving into the process behind making a real-world Ember application
